Abstract

23,868. Burdon, C. B., [Siemens-Schuckertwerke]. Dec. 10. Coils and conductors.-A slot key for dynamoelectric machines comprises a plain thick piece of magnetic metal which is forced inward to cause it to expand laterally, so that it presses or seats itself firmly between the two edges of the slot. The key b may be formed as an arch as shown in Fig. 1, and its edges spread apart by indenting the key in a radial direction. In another construction, the key has a slight outward curvature, which is reversed after insertion in the grooves. Part only of the key f may be bulged or arched, as shown in Fig. 3.
